摘　　要：研究了3个方面的问题,一是中国大陆周边4个地震带地震活跃期与中国大陆地震活跃期的准同步性和它们目前的活动水平;二是欧亚地震带西部与中国大陆的地震活动呈现出明显的超前或滞后性;三是中国大陆邻区6个地震区的强震与中国大陆活跃期的开始或与中国大陆强震的对应关系。上述3个方面的研究结果有助于判定中国大陆地震活跃期是否将要开始和目前是否处于地震活跃期中,以及近期的地震活动水平,因此本文具有较强的实用性。欧亚地震带西部与中国大陆地震活动所呈现的明显超前或滞后性,是一种很值得继续研究的现象,它可能从另一个侧面揭示出了地震活动的某些新特征。Three aspects are discussed in this pater: (l)The quasi-synchronism between the seismically active periods in the China mainland and the seismically active periods of the four belts in its neighboring area; (2)The significant time correlation between seismic activity in the western Eurasia seismic belt and that in the China Mainland; (3)The parallelism between the strong earthquakes in six seismic zones of the neighboring area and the beginning of active periods of the China Mainland, or the strong earthquakes in the China Mainland. The results can be used to decide whether the seismically active period is to begin, whether the area to be in an active period, and to decide the recent seismicity level. There fore this work is more practical. The quasi-complementship between the seismicity in the western Eurasia seismic belts and that in the China Mainland needs studying deeply, which may reveal some new features of seismic sctivity.
